Sang-Chan Jin, Eun-Joo Lee · Journal of the Korea Society of Computer and Information · 2009
At present, Web services become main means to construct web applications. As the number of web services grows and various kind of web services have been produced, QoS properties of web services are one of important criteria to select more appropriate web services. However, the selected web services may become inappropriate for the Requester's requirements, because QoS is kind of dynamic properties. this paper proposes a framework that proposed that finds an appropriate web service for Requester's QoS requirements, and dynamically replaces an inappropriate web service with right one. The problems which happen in substitution step are also identified and the solutions are described with an illustrative example.
